I got the same letter and I immediately thought the same thing-SCAM and what are they trying to get from me? I agree too, I am reluctant to call the number too. The phone number on mine was the same except the last four digits were 2227.
My mother in law got a call from this number. The caller gave a name and said that he was calling from the US embassy in Dominican Republic. He told her that her grandson was in an accident in the Dominican Republic and that she needed to send him $2400. immediately. Caller had her name and the grandson's name. She almost complied until she told her son, a police Lt, who stopped her.
